Neighbors are up in arms after Leonardo DiCaprio's lavish 50th birthday party.

The West Hollywood bash hosted by Leonardo DiCaprio for his 50th birthday must have been a spectacle, as he invited the elite of Hollywood to the event.

The real excitement was happening outside, where neighbors of the Academy Award-winning celebrity gathered near the valet to grumble about the party and the traffic it was causing.

DiCaprio hosted a star-studded party with guests such as Katy Perry, Orlando Bloom, Robin Thicke, April Love Geary, Bill Maher, and several supermodels.

Ines de Ramon and Brad Pitt arrived at the party in his Porsche.

Residents in the neighborhood where the party was held expressed their dissatisfaction with security in a video obtained by Planet Chronicle Digital. According to a source, the residents were informed about the party beforehand.

""My neighbor and I both have private property being driven over, and we're wondering who would be held responsible if any damages occur," the man said to the woman in a long green jacket."

The woman assured the man that she would give him the contact information, but stated, "I am not involved in this party beyond reading the list."

"Somebody just hit my car and ran over my front lawn," the man said, "I know, I know."

The same man is later heard asking guests to stop making U-turns on his property.

"I can definitely ask if you will give me one second," the same woman responds.

The resident approached the man in a suit on the property's perimeter and asked him to accompany her back to her home, expressing concern about her security.

The resident is escorted down the street by men in security jackets while a long line of cars tries to get through the neighborhood or pull up to the party. Several engines rev in the background. Upon reaching his driveway, the resident says, "They keep going in and out, and somebody almost hit my car a minute ago."

"The man in the suit apologized, saying, "Oh no, I'm sorry about that. You can rest assured, you'll be taken care of.""

The younger man near the valet area was also upset, as the source told Planet Chronicle Digital that the valet for the event was located far from the actual party.

The man inquired, "Just so you know, it's low-key, but I can make it higher if I wanted to. What's going on here?" Despite being informed that a party was occurring, he remained unphased.

He stated that he understood it wasn't his fault, but he needed to know who was responsible for this. He intended to take additional action by making a case.

Another young man slams his door and walks towards the commotion outside, asking for the manager. When someone suggests calling the Los Angeles Police Department (LAPD), he becomes surly.

"What do you guys suggest we do?" someone from the party inquired.

"Yeah, calling the police never results in their appearance," the young man remarked.

"Call 9-1-1," someone said.

"He explained that he had already done it and that they had informed him of their arrival, though it would take them some time to arrive."

On Saturday at 10:11 p.m., and again shortly after midnight on Sunday, two complaints were filed with the LAPD about a "loud party" in the area where "The Wolf of Wall Street" star's birthday celebration was taking place.

Planet Chronicle Digital reached out to representatives for DiCaprio for comment.
